Application filed May 19, 1917. Serial No. 170,292.

To all whom it may concern:

Be it known that I, LEWIS A. PAYTON, a citizen of the United States, residing at I-Iaskew, in the county of Woodward and State of Oklahoma, have invented certain new and useful Improvements in Fluid- Pumps, of. which the following is a specification.

This invention relates to fluid pumps and use in wells, and has for its objects to produce a pump of great efficiency, durability and capacity. More'specifically my object is to produce a pump for compressing air and utilizingsuch air to efiectthe delivery'of water from a well. lVith the general objects mentioned in view the invention consists in certain novel and peculiar features of construction and combinations of parts as hereinafter described and claimed; and in order that the invention may be fully understood reference is to be had to the accompanying drawing, in which:

Figure 1, is a" front view of the bodying my invention, one of the air cylinders and pistons being shown in section and other parts broken away.

Fig. 2 is a side elevation of the pump.

pump em- In the said drawing, "1 indicates a. pair ofair cylinders provided at theirlower ends with heads or caps 2, connected by pipes 3 with the heads or caps 4 of a pair of water cylinders 5, The lower ends of the water cylinders areclosed by caps 6, having reduced necks 7 equipped with perforated caps 8. 9 are pipe ways extending from cylinder 5 near the lower ends thereof, and the upper are connected by pipes 10 to a standpipe 11 closed at its upper end by a pipe 12 provided with a delivery spout 13. The caps 2 of the air cylinders, are provided with upstanding tubular portions 14 providing air-intake ports, and controlling said ports are valves 15 retained in operative relation by cages 16. Similar valves 17 within cages 18, are adapted to control the flow of water through the necks of caps 6, and screens 19 are clamped over the lower ends of the necks 17 by the caps for the purpose of excluding sand and other foreign matter from the water cylinders 5.

Couplings 20 are disposed in the pipe lines 9 and containvalves 21 limited as to upward movement by cross pins 22 of the couplings, said valves being adapted when seated a prevent back flow of water through above them any their respective pipe ways, that is to retain standpipe below a point hereinafter mentioned. 23 represents a series of bearings for a crank shaft 24, the same being shown as provided with two oppositely projecting water which stands in the cranks 25, respectively connected by piston 1 rods 26, with pistons 27 'fitting in the air cylinders '1. Said pistons are of any suitable type, but are preferably provided with cup leathers 28 of sufficient capacity to hold a small quantity of water, this water serving 1 to lubricate the pistons and at thesame time holdthe cup leathers withan air tight relation to the cylinders and keepthe latter cool. To supply the water to the air cylinders for he purpose mentioned, the standpipe is provided with a pair of leak pipes 30 through which a suflicient'quantity of water can flow to maintain the desired quantity on the cup leathers.

Assuming that a described is lowered into a well, until the water level is above the water cylinders, it will be apparent that thewater will seek its level in the standpipebut will preferably pump of the character fall short of such level in the plpe 3 owing to the fact that air is trapped above it in the cylinders 1. Assuming now that the crank shaft is operated, it will be apparent that the upstroke ofthe depressed piston will'result in the opening of the valve of such cylinder and its charge with air, the descent of the piston in the companion air cylinder will compress air below its respective piston 1 and pipe 3 and thus force water standing in said pipe and its respective cylinder 5 up through the connecting pipe 9 and into the standpipe 11, the controlling valve 21 opening under such pressure, and the respective water controlling valve 17 closing to prevent back flow of water into the well.

As the crank shaft starts on its second a half revolution the operations of said air cylinders as described are reversed, so that the piston which charged its cylinder with air, compresses such charge and efiects a flow of water from its respective cylinder 5 and pipe way 9 into the standpipe. It will thus be seen that by the use of two air cylinders a constant flow of water into the standpipe and from same when said standpipe is once filled with water, it being understood that each time an air cylinder is charged with air the valve 17 of the respective water cylinder opens to permit water item the well to seek 1 tervals. There will be little we'ar upon the air cylinders as no sand can accumulate therein, and the cup leathers are readily accessible for replacement when necessary without dismantling the pump. The water cylinders and connections will seldom need attention, particularly as the screens will guard against the entrance into the water cylinders of particles large enough to effect the operation of the valves-in fact screens may be employed of sufficient fineness to exclude coarse sand.

From the above description it will be apparent that I have produced. a fluid pump embodying the features of advantage enumerated as desirable, and while I have illustrated and described the preferred form of the invention it is to be understood that I reserve the right to all changes properly falling within the spirit and scope of the appended claims.

I claim:

1. A pump comprising a water cylinder havinga check-valve controlled intake, a standpipe connected to said cylinder, a cylinder having a check-valve controlled intake for air, a pipe connecting said cylinder with the watercylinder in a plane above the valve of the latter, a pistonfor operation in the air cylinder, to charge same with air in one stroke and compress such air in the other copies: this patent may be obtained for five cents each, by addressing the i Washington, D. C. r

stroke and cause it to force water in the water cylinder to close the intake valve thereof and flow through said standpipe, and a leak pipe to convey water from the standpipe into the upper end of the cylinder having the intake for air.

2. A pump comprising a water cylinder having a check-valve controlled intake, a standpipe connected to said cylinder, a check-valve controlling said standpipe, a cylinder havinga check-valve controlled in take for air, a pipe connecting said cylinder With the water cylinder in a plane above the valve of thelatter, a piston for operation in the air cylinder, to charge same with air in one stroke and compress such air in the other stroke and cause it to force water in the water cylinder to close the intake valve thereof andv flow through said standpipe, and a leak pipe to convey water from the standpipe into the upper end of the cylinder having the intake for air.

3. A pump comprising a pair of water cylinders having intake openings, checkvalves controlling saidopenings, a standpipe, pipes connecting the cylinders respec tively with the standpipe, check-valves for said connecting pipes, a pair of cylinders having air intake openings, check-valves controlling said. openings, pipes connecting the air cylinders with the water cylinders, pistons, in the air cylinders, a crankshaft, connecting rods between the crank shafts and the pistons to operate the latter inreverse directions simultaneously, and leak pipesfor, conveying water from the standpipe to said cylinders above the pistons thereof. e

In testimony whereof, I afiix my signature.
